This volumetric flow rate calculator is designed to help you quickly and accurately calculate the volume flow rate using the Bernoulli Equation.
Calculating volume flow rate requires the pipe diameter (d) and the flow speed (v).
Pipe Diameter (d)
Flow speed (v) (m/s)
Volume Flow Rate (q)
In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.
The Bernoulli equation states that
The principle is only applicable to isentropic flows. The equation is not valid when the flow is turbulent (the effect is irreversible) and for non-adiabatic processes (e.g. thermal radiation) because the effect is small.

Bernoulli equation can of course be rearranged to solve for each variable. Below presents a calculation to solve for q.
